OIL-SHIELD FOR SEWING-MACHINES.

Application filed November 18, 1912.

To all whom it may concern:

Be it known that I, IDA P. NICHOLS, a citizen of the United States, and a resident of Ithaca, county of Tompkins, and State of New York, have invented an Improvement in Oil-Shields for Sewing-Machines, of which the following description, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

This invention relates to oil shields for sewing machines and other uses, and among other objects provides a device which is simple and cheap in construction and readily applicable to the presser foot or needle bar to prevent oil from dripping down tofabrics beneath the same.

The character of the invention may be best understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying drawing, wherein:

Figure l is a side elevation of a portion of a sewing machine equipped with an illustrative oil shield embodying the invention; Fig. 2 on an enlarged scale is a plan of a band blank forming a part of the shield shown in Fig. 1; Fig. 3 is atop view of the shield; Fig. 4 is a side elevation of the shield; and Fig. 5 is a bottom view of the shield.

Referring to the drawing, 1 designates a portion of the head of a sewing machine provided with the usual presser foot bar 3, presser foot 5 and needle bar 7.

The illustrative oil shield shown herein as embodying the invention comprises (Fig. 2) a discontinuous band 9 of resilient flexible steel or other suitable material of a length suflicient to embrace presser feet and needle bars of different sizes and leave ends 11 and 13 of suflicient extent to be brought into superposed relation. Preferably the band-has an inherent resilience or spring tending to cause the ends 1 1 and 13 to approach one another and bring the band into tight gripping contact with the oil absorbent lining and the latter in turn into gil arresting gripping engagement with the To assist in preventing the lining from dropping out of the band the latter may have at its lower edge teeth 17 bent substantially perpendicular to the body of the band.

The inherent resilience of the band is Specification of Letters Patent.

cient to clamp the shield to its bar in most uses, but in some cases additional securing means may be desired. This may be effected by providing a locking bolt 21 entered through apertures 23 in the overlap in band ends 11 and 13. p b the conformity of the band to bars of different sizes one of said apertures may be elongated. By this construction the bolt may be set up and tightly positively pinch the band to its lining and the latter to its bar.

In use the open ends of the shield are presented to the bar and sprung apart sufliciently to permit the shield to be laterally presented to and sprung around the bar. The inherent resilience of the band causes the same to tightly grip its lining to the bar. In case the lock bolt is provided it is then introduced through the ends of the band and set up to draw the band ends toward one another and thereby secure the shield in tight embracing contact with the bar. The lining preferably is of a length suificient to extend around the bar and overlap the superposed ends of the band of the shield and thus is of a length to conform to bars of different sizes.

The teeth for supporting the lining preferably are somewhat shorter than the thickness of the lining. As a result, the metal band when tightened on the bar compresses the lining into secure gripping contact with the bar and the shield is prevented from slipping down on the ban.

The lining is not set in the closed bottom of a cup and therefore does not absorb and become saturated with oil settling in such bottom, but is free for absorbing to its full capacity. When the lining is saturated it may be readily removed and a fresh lining substituted therefor.

The lining is of a width sufficient to present a substantial extent of contact with the bar and thereby prevents any possibility of oil getting past said lining.

One of the principal advantages of the shield described is that it is not necessary in applying the same to a bar to remove or disturb devices at the end of the bar to permit the shield to be inserted over the end, but on the contrary the shield may be directly laterally presented and applied to the bar at any desired point along the same.

For purposes of illustration, the shield To prevent interis shown herein as applied to a needle bar,

but obviously it may be also applied to the by Letters Patent is 1. An oil shield comprising a discontinuous band having ends adapted to spring away from one another and permit lateral application of the shield to a member at a point between the ends of the latter and an oilabsorbent internal lining for said band separate from the latter and completelyencircling said member, said band having inherent resilience for gripping said lining to said member and preventing a sliding of the shield longitudinally of said member.

2. An oil shield comprising a discontinuous band and an oil-absorbent lining there- 'for separate therefrom, said band having ends adapted to spring away from one another and permit lateral application of the shield to a member at a point between the ends thereof and having provision for gripping said lining to said member sufficiently to prevent movement of the shield longitu- V dinally of said member.

a, An 011 shield comprising a single dismovement thereof longitudinally of said a member. y

In testimony whereof, I have signed my name to this specification, in the presence ofv two subscribingwitnesses. I
